System Information
Operating system: Windows-10-10.0.18362-SP0 64 Bits
Graphics card: GeForce RTX 2070/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 432.00

Blender Version
Broken: version: 2.91.0 Alpha, branch: master, commit date: 2020-10-15 21:02, hash: ba8233174c
Worked: 2.90.1
This is probably an issue with f12b0373f3 -- it started being an issue with d39043b5ae again

Short description of error
If a GizmoGroup is 2D (doesn't have '3D' in bl_options), any glEnable/glDisable calls during dizmo drawing will result in the glitch (at least for me, the 3D viewport turns black, and the navigation gizmos lose their text/icons).

Exact steps for others to reproduce the error

Open the default scene in Blender 2.91
Run the attached script (it will register a gizmo for Light objects)
Select the light
The 3D viewport will turn black

Can confirm, this is probably an issue with f12b0373f3 -- it started being an issue with d39043b5ae again

@fclem: I know there has been quite some work on BGL etc., dont see glEnable/glDisable mentioned in blender/blender-addons#80730 (BGL deprecation) though, nor documented that this usage needs to be tweaked in 2.91?
So: looks like a bug to me, will set to High prio (really think we should keep the bgl API working, there are potentionally lots of Addons using this)
